Detailed Descriptions for the elements in the extension.
Extension | |
Element Id | Extension |
Definition | If true indicates that the request is asking for the specified action to not occur. |
Control | 0..1 This element is affected by the following invariants: ele-1 |
Is Modifier | true (Reason: If true this element negates the specified action. For Example, instead of a request for a procedure, it is a request for the procedure to not occur.) |
Comments | The attributes provided with the request qualify what is not to be done. For example, if an effectiveTime is provided, the "do not" request only applies within the specified time. If a performerType is specified then the "do not" request only applies to performers of that type. Qualifiers include: code, subject, occurrence, perormerType and performer. In some cases, the Request.code may pre-coordinate prohibition into the requested action. E.g. "NPO" (nothing by mouth), "DNR" (do not recussitate). If this happens, doNotPerform SHALL NOT be set to true. I.e. The resource shall not have double negation. (E.g. "Do not DNR"). |
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (xpath: @value|f:*|h:div) ext-1: Must have either extensions or value[x], not both (xpath: exists(f:extension)!=exists(f:*[starts-with(local-name(.), 'value')])) |
Extension.id | |
Element Id | Extension.id |
Definition | Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces. |
Control | 0..1 |
Type | string |
Extension.extension | |
Element Id | Extension.extension |
Definition | An Extension |
Control | 0..0 |
Type | Extension |
Slicing | This element introduces a set of slices. The slicing rules are:
|
Extension.url | |
Element Id | Extension.url |
Definition | Source of the definition for the extension code - a logical name or a URL. |
Control | 1..1 |
Type | uri |
Comments | The definition may point directly to a computable or human-readable definition of the extensibility codes, or it may be a logical URI as declared in some other specification. The definition SHALL be a URI for the Structure Definition defining the extension. |
Fixed Value | http://hl7.org/fhir/StructureDefinition/request-doNotPerform |
Extension.valueBoolean | |
Element Id | Extension.valueBoolean |
Definition | Value of extension - may be a resource or one of a constrained set of the data types (see Extensibility in the spec for list). |
Control | 0..1 |
Type | boolean |
